Another example of "peaceful" Islamists. India has 0 troops in Afghanistan but they are predominantly "kuffar" so that makes them targets of Islamists.
Again if Pakistan continues to be the epicenter of Jihad, Inc. eventually this is going to lead to Pakistan being isolated from the rest of the world and direct military intervention, whether from the US, China, or India. China and India are rapidly rising powers with booming economies. Pakistan cannot afford being economically isolated from these two giants.
You're wrong about India having 0 troops in Afghanistan. Your wrong for putting "kuffar" in quotes, Islamically they are Kafir. Furthermore you're wrong about about prematurely linking it the Pakistani state apparatus. Pakistan has been a greater victim of extremist violence than India. Of course, if you're a Pakistan hater, you will choose to gloss over that fact.
That being said, any loss of human life particularly those who are diplomats is sad and my condolences the families of those who passed away, Indian or not, we're all humans first.
